I guess the first question is what she intends to use it for, as that will ultimately determine what would be recommended.
I think the 12.2 megapixel camera you are referring to is the Rebel T3? So, you are looking at the T3, T3i and T4i.
Between the 3 bodies, the T4i is the newest and has fancy features like the touchscreen. It also has more movie options (1080p, various frame rates, etc) compared to the T3. It can use UHS-I SD cards.
The T3 does not have an articulating LCD screen like the other two, so that may be a factor.
There are other factors like size, weight, form, the feeling of the buttons, etc.
Viewfinder coverage, mirror versus prism are also important factors to consider since with a DSLR, the majority of the time you are not using the LCD to compose photos.
